Description

Technical Field

[0001] This utility model relates to the field of wire harness production and processing, and in particular to an adjustable positioning fixture for wire harness processing. Background Technology

[0002] Wire harnesses are widely used in the automotive, electronic equipment, and aerospace industries. They are integrated components formed by the orderly assembly of multiple insulated wires, cables, shielded wires, etc., arranged in a specific direction and layout, along with accessories such as terminals, connectors, sheaths, and bundling devices. Their core function is to realize signal transmission, power supply, and circuit connection between different components. Through standardized integrated design, installation processes can be simplified, wiring clutter can be reduced, and space utilization can be improved.

[0003] During the manufacturing process of wire harnesses, they need to be positioned and bundled. Chinese Patent CN220130425U discloses a wire harness positioning and bundling fixture, relating to the field of power wire harness processing technology. This fixture includes moving an adjusting plate to adjust the distance between two processing plates. After adjusting to a suitable position, a connector is inserted into a socket to fix the adjusting plate. Then, an L-shaped groove of appropriate size is selected according to the diameter of the power wire harness. The power wire harness is placed in the L-shaped groove, and then a lifting tube is moved, causing its bottom end to push a clamping plate downwards, thus moving the clamping plate toward the power wire harness. However, this fixture requires moving the adjusting plate to adjust the distance between the two processing plates and inserting a connector into the socket to fix the adjusting plate when positioning the wire harness. Therefore, adjusting the distance between the two processing plates is inconvenient, and it cannot quickly position and clamp the wire harness, making operation cumbersome and reducing the positioning speed during wire harness processing.

[0004] To address this technical problem encountered in actual production work, there is an urgent need to design an adjustable positioning fixture for wire harness processing. Summary of the Invention

[0005] The purpose of this invention is to provide an adjustable positioning fixture for wire harness processing, which solves the problems of inconvenient distance adjustment between processing plates, inability to quickly position and clamp the wire harness, cumbersome operation, and low positioning speed in existing fixtures when positioning the wire harness. It achieves rapid positioning and clamping of the wire harness, improves positioning speed and processing efficiency, and reduces operational difficulty.

[0006] The above-mentioned objective of this utility model is achieved through the following technical solution: An adjustable positioning fixture for wire harness processing includes a positioning table 1. A fixed plate 2 is fixedly connected to the upper surface of the positioning table 1. Two movable plates 3 are arranged on the positioning table 1. A support clamping mechanism 4 is fixedly connected to the upper surface of the two movable plates 3 and the upper surface of the fixed plate 2. A positioning support 5 is fixedly connected to one side of the support clamping mechanism 4. An arc-shaped positioning groove 10 is opened on the upper surface of the positioning support 5. A driving mechanism 6 is arranged below the positioning table 1. A transmission slide 7 is fixedly connected to the bottom surface of the positioning table 1. Two threaded sliding blocks 8 are slidably connected to the inner wall of the transmission slide 7. The upper surfaces of the two threaded sliding blocks 8 are fixedly connected to the bottom surfaces of the two movable plates 3 respectively. The threaded sliding blocks 8 are threadedly sleeved on the transmission screw 12.

[0007] The drive mechanism 6 includes a drive motor 61, which is fixedly installed on the bottom surface of the transmission slide 7. The output end of the drive motor 61 is fixedly installed with a drive shaft 64, and the top end of the drive shaft 64 is fixedly installed with a drive gear 62. The inner bottom wall of the transmission slide 7 is fixedly inlaid with a first bearing 65, and the outer surface of the drive shaft 64 is fixedly connected to the inner ring of the first bearing 65.

[0008] The ends of the two transmission screws 12 are respectively fixedly connected to transmission gears 63, and one end of each transmission gear 63 meshes with the outer surface of the drive gear 62.

[0009] The inner wall of the transmission slide 7 is fixedly inlaid with two second bearings 13, and two bearing seats 14 are fixedly installed on the inner bottom surface of the transmission slide 7. The inner rings of the two bearing seats 14 and the inner rings of the two second bearings 13 are respectively connected to the outer surfaces of the two transmission screws 12.

[0010] The support clamping mechanism 4 includes a support stand 44, a support cover 41 is fixedly connected to one side of the support stand 44, an electric cylinder 42 is fixedly installed on the inner side wall of the support cover 41, a sliding positioning block 43 is fixedly installed on the telescopic end of the electric cylinder 42, and one side of the sliding positioning block 43 is in contact with one side of the positioning support 5.

[0011] The upper surface of the positioning support 5 is provided with a T-shaped groove 45, and the inner wall of the T-shaped groove 45 is slidably connected to a limiting block 46.

[0018] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. To make the above-mentioned objects, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] See Figures 1 to 5 As shown, the adjustable positioning fixture for wire harness processing of this utility model achieves rapid and automated spacing adjustment through a drive mechanism. Starting the drive motor drives the drive shaft and drive gear to rotate. Through the meshing transmission of the drive gear and two transmission gears, the two transmission screws rotate in opposite directions, thereby driving the threaded sliding block to slide along the transmission slide block. Finally, the drive moving plate moves smoothly through the adjustment sliding hole, quickly adapting to the wire harness length, solving the problem of cumbersome steps of manual adjustment and pin fixing, and improving the spacing adjustment efficiency. The structure includes a positioning platform 1, with a fixed plate 2 fixedly connected to its upper surface. Two movable plates 3 are mounted on the positioning platform 1. Supporting clamping mechanisms 4 are fixedly connected to the upper surfaces of both movable plates 3 and the upper surface of the fixed plate 2. A positioning support 5 is fixedly connected to one side of the supporting clamping mechanism 4, and an arc-shaped positioning groove 10 is formed on the upper surface of the positioning support 5. A driving mechanism 6 is located below the positioning platform 1, and a transmission slide 7 is fixedly connected to the bottom surface of the positioning platform 1. Two threaded sliding blocks 8 are slidably connected to the inner wall of the transmission slide 7. The upper surfaces of the two threaded sliding blocks 8 are respectively fixedly connected to the bottom surfaces of the two movable plates 3, and the threaded sliding blocks 8 are threaded onto the transmission screw 12. The fixed plate 2 is fixed to the positioning platform 1 and, together with the two movable plates 3, adapts to wire harnesses of different lengths. The supporting clamping mechanism 4 provides a stable mounting carrier for the positioning support 5. The arc-shaped positioning groove 10 of the positioning support 5 conforms to the shape of the wire harness, enabling quick initial positioning of the cable and preventing displacement during placement. By cooperating with the transmission slide 7, the threaded sliding block 8 and the transmission screw 12, a transmission path can be provided for the movement of the moving plate 3, so as to realize flexible adjustment of the positioning distance and improve the adaptability of the tooling.

[0020] The drive mechanism 6 includes a drive motor 61 fixedly mounted on the bottom surface of the transmission slide 7. A drive shaft 64 is fixedly mounted on the output end of the drive motor 61, and a drive gear 62 is fixedly mounted on the top end of the drive shaft 64. A first bearing 65 is fixedly embedded in the inner bottom wall of the transmission slide 7. The outer surface of the drive shaft 64 is fixedly connected to the inner ring of the first bearing 65. Transmission gears 63 are fixedly connected to the ends of the two transmission screws 12, and one end of each transmission gear 63 meshes with the outer surface of the drive gear 62. The drive mechanism 6 provides power for the spacing adjustment. The drive motor 61 outputs stable power to drive the drive shaft 64 to rotate. The drive shaft 64 is positioned and supported by the first bearing 65, reducing frictional loss during rotation and ensuring transmission stability. The drive gear 62 at the top end of the drive shaft 64 meshes with the transmission gears 63 of the two transmission screws 12 to achieve power splitting and reverse transmission, so that the two moving plates 3 move synchronously in opposite directions, ensuring the symmetry of the adjustment.

[0021] Two second bearings 13 are fixedly embedded in the inner wall of the transmission slide 7, and two bearing seats 14 are fixedly installed on the inner bottom surface of the transmission slide 7. The inner rings of the two bearing seats 14 and the inner rings of the two second bearings 13 are respectively fixedly connected to the outer surfaces of the two transmission screws 12. Two L-shaped grooves 15 are formed on the upper surface of the positioning table 1. The inner walls of the L-shaped grooves 15 are slidably connected to limit sliding plates 11. The upper surfaces of the two limit sliding plates 11 are respectively fixedly connected to one side of the two moving plates 3. Through the cooperation of the second bearings 13 and bearing seats 14 in the transmission slide 7, the two ends of the transmission screws 12 can be positioned and supported, limiting their radial displacement, ensuring the stability of the axis during rotation, and avoiding jamming of the threaded transmission. The L-shaped grooves 15 of the positioning table 1 and the limit sliding plates 11 of the moving plates 3 slide to provide guidance for the moving plates 3, preventing deflection during movement, ensuring accurate adjustment of the spacing of the positioning supports 5, making the adjustment process of the moving plates 3 smoother, improving the positioning accuracy of the wire harness, and reducing processing errors.

[0022] The support clamping mechanism 4 includes a support stand 44 and a support cover 41 fixedly connected to one side of the support stand 44. An electric cylinder 42 is fixedly installed on the inner wall of the support cover 41. A sliding positioning block 43 is fixedly installed on the telescopic end of the electric cylinder 42. One side of the sliding positioning block 43 contacts one side of the positioning support 5. A T-slot 45 is formed on the upper surface of the positioning support 5. A limit block 46 is slidably connected to the inner wall of the T-slot 45. The upper surface of the limit block 46 is fixedly connected to the bottom surface of the sliding positioning block 43. Two adjusting sliding holes 9 are formed on the upper surface of the positioning table 1. The outer surfaces of the two threaded sliding blocks 8 are slidably connected to the inner walls of the two adjusting sliding holes 9, respectively. The support stand 44 of the support clamping mechanism 4 provides a stable mounting base for the support cover 41. The support cover 41 protects the internal electric cylinder 42 from processing dust. The telescopic end of the electric cylinder 42 drives the sliding positioning block 43 to move, realizing the rapid clamping and loosening of the wire harness, replacing manual operation and improving efficiency. The T-slot 45 of the positioning support 5 cooperates with the limiting block 46 of the sliding positioning block 43 to restrict the sliding direction and ensure uniform force during clamping. The adjusting slide hole 9 provides movement space for the threaded sliding block 8 and also assists in guiding, ensuring smooth overall transmission.

[0023] See Figures 1 to 5 As shown, when using the adjustable positioning fixture for wire harness processing of this utility model, the positioning distance is first quickly adjusted by the drive mechanism 6. Then, the drive motor 61 in the drive mechanism 6 is started. The output end of the drive motor 61 drives the drive shaft 64 to rotate. The drive gear 62 at the top of the drive shaft 64 rotates synchronously. Since the drive gears 63 at one end of the two drive screws 12 are meshed with the drive gear 62, the drive gear 62 drives the two drive gears 63 to rotate in opposite directions, thereby causing the two drive screws 12 to rotate. When the drive screws 12 rotate, the threaded sliding block 8 connected to it slides along the inner wall of the drive slide block 7. At the same time, the threaded sliding block 8 passes through the adjustment sliding hole 9 and drives the moving plate 3 to move until the distance between the two moving plates 3 and the fixed plate 2 is adapted to the wire harness length. There is no need to manually move the adjustment plate and fix the pin, thus realizing the rapid adjustment of the distance. After the spacing adjustment is completed, the wire harness is quickly positioned and clamped: the wire harness is placed in the arc-shaped positioning groove 10 of the positioning support 5, and the arc-shaped structure initially limits its position. The electric cylinder 42 inside the support cover 41 of the support clamping mechanism 4 is activated. The telescopic end of the electric cylinder 42 pushes the sliding positioning block 43 to move. The limiting block 46 at the bottom of the sliding positioning block 43 slides along the T-shaped groove 45 of the positioning support 5, ensuring that the sliding positioning block 43 moves smoothly and fits against the surface of the wire harness. The wire harness is quickly clamped and positioned through the coordinated action of the three support clamping mechanisms 4. The whole process does not require cumbersome manual operation, which not only solves the problem of inconvenient spacing adjustment of traditional tooling, but also realizes the rapid positioning and clamping of the wire harness, greatly improving the positioning speed.

[0024] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.

[0025] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made to this utility model should be included within the protection scope of this utility model.
